Which seton works best for anal fistulas? trial cut short
NCT ID NCT05933343
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two types of drainage setons—Ethibond suture and vessel loop—for treating complex anal fistulas. The goal was to see which material drains infection better, lasts longer, and improves quality of life. However, the trial was terminated early after enrolling only 2 participants, so no firm conclusions can be drawn.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ethibond suture or vessel loop (drainage seton)
- What this could lead to
- If successful, this could show which seton material is more comfortable and effective for draining anal fistulas, potentially improving quality of life.
- What could go wrong
- The trial was terminated early with only 2 participants, so results are very limited. It is unclear if either material is truly better.
